Plutonium-238 (238 Pu) is a radioactive isotope of plutonium that has a half-life of 87.7 years. Plutonium-238 is a very powerful alpha emitter ; as alpha particles are easily blocked, this makes the plutonium-238 isotope suitable for usage in radioisotope thermoelectric generators (RTGs) and radioisotope heater units .

Pu-238 exhibits high heat density and emits primarily alpha particles, which are easily shielded; this makes it safer to handle than most other radioactive materials. High heat density and low shielding requirements both make for a lighter device. Unlike Pu-239, Pu-238 is non-fissile, so it cannot be used in nuclear power plants or nuclear weapons. The greatest limitation of Pu-238,

al. The high heat output (0.557 watts/g) Plutonium-238 has more benign applications and has been used to power batteries for some heart pacemakers, as well as provide a long-lived heat source to power NASA space missions. Like uranium, plutonium can also be used to fuel nuclear power plants, as is done in a few countries.

2008-04-21 · Procurement of Pu-238 from Russia commenced in early 1990’s and will conclude in 2010 – Approximate quantity purchased from Russia by that time will be 30-40 kg – Russia also lost its capability to produce new Pu238 – By agreement, Pu-238 from Russia can not be used for national security applications

Most of the alpha decay populates the U-234 ground state (71.04 %) and the U-234 ﬁrst excited level with energy of 43.50 keV (28.85 %). Branching of Pu-238 decay by spontaneous ﬁssion is 1.85 (5)E-7 %. 238. Pu shipments by adding load out capability and updating safety documents. Handling large quantities of . 238.
